So I had the same "Incomplete" status a few weeks ago on the "MyPitt Portal" and I actually called Pitt (got routed through IT, then admissions, then Phil admissions) about it and it turns out that that is nothing to worry about. If you go back to the ApplyWeb application where you actually submitted your documents and click on "check application" it will say that your application is complete, and that's the one that matters. They basically said, don't worry about the MyPitt portal. I got worried about it too, but apparently it doesn't matter.
